[0002] With the rapid development of display technology, commonly used display panels are evolving from liquid crystal displays (LCDs) to organic light-emitting diodes (OLEDs). Compared to LCDs, OLEDs are more sensitive to foreign matter, leading to more prominent defects, particularly mura.

[0003] When inspecting OLED panels for abnormalities, different inspection stations currently operate independently, generating their own defective candidate points (points and lines) based on their own inspection logic for auxiliary judgment. However, this approach lacks information communication and auxiliary judgment between inspection stations.

[0071] It should be noted that Figure 1 The scenario diagram of the panel anomaly detection system shown is only an example. The panel anomaly detection system and scenario described in the embodiment of the present application are intended to more clearly illustrate the technical solution of the embodiment of the present application, and do not constitute a limitation on the technical solution provided by the embodiment of the present application. Ordinary technicians in this field can know that with the evolution of the panel anomaly detection system and the emergence of new business scenarios, the technical solution provided by the embodiment of the present application is also applicable to similar technical problems.

[0072] First, an embodiment of the present application provides a panel abnormality detection and display method. The panel abnormality detection and display method is performed by a panel abnormality detection device, and the panel abnormality detection device is applied to an electronic device. The panel abnormality detection and display method includes: performing a first detection on a first panel in a first process to distinguish different abnormalities of the first panel and obtain first abnormality mark information; repairing the first panel according to the first abnormality mark information, and marking the abnormality after the repair to obtain first repair mark information and a repaired second panel; compensating the second panel in a second process to obtain a compensated third panel, and determining a first compensation value corresponding to each pixel in the third panel to obtain multiple first compensation values;

[0073] performing a second inspection on the third panel based on the plurality of first compensation values, determining different abnormalities corresponding to the third panel, and obtaining second abnormality marking information; repairing the third panel based on the first abnormality marking information and the second abnormality marking information, and marking the abnormalities after the repair, to obtain second repair marking information and a repaired fourth panel;

[0074] The display priority of the mark information is acquired to display the first abnormality mark information, the first repair mark information, the second abnormality mark information, or the second repair mark information with the highest priority on the fourth panel according to the priority.

[0075] like Figure 2 As shown, a flow chart of an embodiment of a panel abnormality detection and display method provided in an embodiment of the present application may include:

[0076] 21. Perform a first inspection on the first panel in a first process to distinguish different abnormalities of the first panel and obtain first abnormality mark information.

[0077] Specifically, the panel in the embodiments of the present application includes multiple different production processes, and various anomalies may occur in each process. Therefore, the panel needs to be tested after each process to detect anomalies such as bright spots, dark spots, and lines that may have occurred during the panel production process. Throughout the entire panel production process, the panel usually needs to be tested multiple times.

[0078] In an embodiment of the present application, a first inspection can be performed on the first panel after the panel completes the first process, using a predetermined first inspection method to detect whether the first panel that has completed the first process has any abnormalities. If the first panel has any abnormalities, different types of abnormalities need to be distinguished and marked to obtain first abnormality marking information.

[0079] The first abnormality mark information is obtained by performing a first detection on the first panel using a preset first detection method. Different abnormality types may include bright spots, dark spots, lines, etc., and different abnormality types correspond to different abnormality mark information.

[0080] However, in the embodiment of the present application, the anomaly detected by the preset first detection method needs to be compared with the anomaly detected in the process before the first process. Only the matching anomaly can be considered as the anomaly detected in the first process, and then the anomaly is marked to obtain the first anomaly marking information.

[0081] like Figure 3 As shown, a flow chart of an embodiment of determining first abnormality marking information provided by an embodiment of the present application may include:

[0082] 31. Obtain initial abnormal position information corresponding to the first panel.

[0083] 32. Detect the first panel in a first process to determine first abnormal position information corresponding to the first panel.

[0084] 33. Determine whether the first abnormal location information matches the initial abnormal location information.

[0085] 34. If the first abnormality location information matches the initial abnormality location information, mark the first abnormality information according to a preset abnormality type to distinguish different abnormalities corresponding to the first abnormality location information, and obtain first abnormality marking information.

[0086] In the embodiment of the present application, the first panel undergoes other processes before the first process, and thus initial abnormality location information corresponding to the abnormality is obtained through other tests. After the first process, the first panel needs to be tested again to determine the first abnormality location information corresponding to the first panel; the first abnormality location information is then compared with the initial abnormality location information to determine whether the two match.

[0087] If the two match, it can be considered that the anomaly detected in the first process is correct, and the anomaly can be marked differently according to different anomaly types to obtain first anomaly marking information.

[0088] In a specific embodiment of the present application, for the part of the abnormality where the first abnormality location information matches the initial abnormality location information and the abnormality can be repaired, it can be marked as A0; and for the part of the abnormality where the first abnormality location information matches the initial abnormality location information but the abnormal area of ​​the abnormality is larger than the preset abnormal area standard, resulting in the abnormality being unrepairable, it can be marked as A1.

[0089] In other embodiments, if no corresponding abnormality is detected in the initial abnormality location information, but certain defective points are detected in the first abnormality location information, i.e., using the first detection method, these defective points can be marked as A3. Similarly, for certain defective lines that do not correspond to the abnormality detected in the initial abnormality location information but are detected in the first abnormality location information, i.e., using the first detection method, these defective lines can be marked as A4.

[0090] In the above embodiment, since new anomalies may occur during the first process of the panel, the initial anomaly location information does not contain the corresponding location information of these anomalies. However, if these anomalies are subsequently detected using the first detection method, these newly detected anomalies also need to be marked. In the embodiment of the present application, different types of anomalies need to be marked differently to distinguish between multiple types of anomalies.

[0091] 22. Repair the first panel according to the first abnormality marking information, and mark the abnormality after the repair, to obtain the first repair marking information and the repaired second panel.

[0092] After detecting an abnormality in the first panel, the first panel needs to be repaired to partially resolve the abnormality and continue with subsequent processes. In the actual repair process, the abnormality may be repaired successfully or unsuccessfully; therefore, different abnormalities correspond to different repair results.

[0093] In an embodiment of the present application, repairing the first panel according to the first abnormality marking information, marking the abnormality after the repair, and obtaining the first repair marking information and the repaired second panel may include:

[0094] The first panel is repaired according to the first abnormality mark information to obtain a repaired second panel; and it is determined whether the abnormality corresponding to the first abnormality mark information is repaired successfully, so as to perform different abnormality repair marks and obtain first repair mark information.

[0095] In a specific embodiment of the present application, the first abnormality marking information generally includes multiple abnormalities of the first panel. After the abnormalities in the first panel are repaired to obtain a repaired second panel, a repair judgment can be performed on the second panel to determine whether the multiple abnormalities in the first panel are successfully repaired.

[0096] In a specific embodiment, for the anomaly represented by the first anomaly flag information, if the anomaly is successfully repaired, it may be marked as L1; if the repair fails or is not repaired, it may be marked as L2. It should be noted that the L1 flag actually means that an anomaly exists but has been successfully repaired.

[0097] In the embodiments of the present application, different tags corresponding to the panel are generally queried to determine the corresponding abnormality of the panel and the abnormality repair status. Therefore, in the embodiments of the present application, after the abnormality corresponding to the panel is detected and the corresponding repair and repair tag is performed, this information needs to be uploaded to the control system so that the panel condition can be determined by querying different tags later.

[0098] 23. Compensate the second panel in a second process to obtain a compensated third panel, and determine a first compensation value corresponding to each pixel in the third panel to obtain a plurality of first compensation values.

[0099] Based on the above embodiment, after the repaired second panel is obtained, the second panel still needs to undergo other subsequent processes. In one specific embodiment, the second panel enters the second process, during which threshold voltage compensation (i.e., Vth compensation) is first performed on the second panel. The compensated third panel is then tested again to determine whether any abnormalities remain.

[0100] Specifically, when performing threshold voltage compensation, it is necessary to calculate the magnitude of the threshold voltage compensation value corresponding to each pixel in the second panel, that is, the magnitude of the Vth value; and the embodiment of the present application can use the magnitude of the threshold voltage compensation value for abnormality detection.

[0101] 24. Perform a second detection on the third panel according to the multiple first compensation values, determine different abnormalities corresponding to the third panel, and obtain second abnormality mark information.

[0102] like Figure 4 As shown, a flow chart of an embodiment of obtaining second abnormality marking information provided by an embodiment of the present application may include:

[0103] 41. Compare the target first compensation value with the first compensation values ​​corresponding to other pixels within a preset range around the target pixel to determine whether the target pixel is abnormal.

[0104] In an embodiment of the present application, a panel includes multiple pixels, each of which corresponds to a first compensation value. The first compensation value can be used to compensate the pixel, thereby compensating the entire panel. Any pixel in the second panel can be designated as a target pixel, and the compensation value corresponding to the target pixel can be used as the target first compensation value. By comparing the first compensation value with the first compensation values ​​corresponding to other pixels within a preset range around the target pixel, it can be determined whether the target pixel is abnormal.

[0105] Specifically, the target pixel can be used as the center, and the first compensation values ​​corresponding to the eight pixels surrounding the target pixel can be obtained to compare the target first compensation value corresponding to the target pixel with the first compensation values ​​corresponding to the other eight pixels. The specific comparison method and comparison standard can refer to the existing technology and are not limited here.

[0106] 42. If the target pixel is abnormal, determine the abnormality type corresponding to the target pixel and obtain relay abnormality mark information corresponding to the target pixel.

[0107] After determining that the target pixel is abnormal, it is necessary to further determine the abnormality type corresponding to the target pixel, and mark the target pixel differently according to the abnormality type to obtain relay abnormality mark information.

[0108] 43. Determine whether the first abnormality mark information and the relay abnormality mark information match.

[0109] 44. If the first abnormality mark information and the relay mark information match, update the first abnormality mark information to the relay abnormality mark information.

[0110] 45. If the first abnormality mark information and the relay abnormality mark information do not match, retain the relay abnormality mark information.

[0111] In this embodiment of the present application, after obtaining the relay abnormality marking information, it is necessary to compare the abnormality detected here with the first abnormality marking information obtained by the first test. If the two match, the first abnormality marking information originally corresponding to the panel can be updated to the relay abnormality marking information determined by the second test. If the two do not match, it means that the first abnormality marking information did not detect abnormalities, but the second test did detect these abnormalities. Therefore, the abnormality detected in the second test is retained, that is, the relay abnormality marking information is retained.

[0112] In a specific embodiment, the second abnormality marking information may include B1-B5. Among them, B1 represents a defective point detected in the compensated third panel, but the abnormality does not exist in the first abnormality marking information; that is, the relay abnormality marking information corresponding to the abnormality does not match the first abnormality marking information, and the relay abnormality marking information B1 needs to be retained. B2 may be a defective line detected in the compensated third panel, but the abnormality does not exist in the first abnormality marking information, that is, the relay abnormality marking information corresponding to the abnormality does not match the first abnormality marking information, and the relay abnormality marking information B2 needs to be retained.

[0113] Similarly, for B3-B5, which are also abnormalities detected by the third panel after compensation, the abnormalities represented by B3-B5 are different from those represented by B1B2. Each mark represents a specific abnormality.

[0114] It should be noted that the relay anomaly marking information in the embodiment of the present application actually only includes information about the abnormal area and does not include the actual marking. The marking corresponding to the abnormality is determined based on the actual comparison and the actual abnormality after comparing the relay anomaly information with the first anomaly marking information.

[0115] After the second abnormality mark information is determined by the second detection, it is also necessary to perform corresponding repairs on the abnormality represented by the second abnormality mark information. Figure 5 As shown, a flow chart of an embodiment of obtaining the second repair mark information provided by the present application may include:

[0116] 51. Determine whether the first abnormality mark information matches the second abnormality mark information.

[0117] 52. If the first abnormality mark information matches the second abnormality mark information, repair the third panel according to the first abnormality mark information.

[0118] 53. If the first abnormality mark information does not match the second abnormality mark information, repair the third panel according to the second abnormality mark information.

[0119] 54. Mark the abnormality after repair to obtain second repair mark information and a fourth panel after repair.

[0120] In the embodiments of the present application, a first detection method is used to obtain first abnormality flag information, and a second detection method is used to obtain second abnormality flag information. Typically, the detection accuracy of the second detection method is lower than that of the first detection method. However, since new abnormalities may arise during the panel production process, the second detection method may detect some abnormalities that were not detected by the first detection method.

[0121] Therefore, in an embodiment of the present application, it is necessary to first determine whether the first abnormality mark information and the second abnormality mark information match. If the two match, it means that the abnormality is detected using both the first detection method and the second detection method; and because the detection accuracy of the first detection method is greater than the detection accuracy of the second detection method, the third panel can be repaired according to the first abnormality mark information.

[0122] If the two do not match, it indicates that a new abnormality occurred during the second process, and only the second detection method detected this abnormality. Therefore, only the second abnormality detection information can be used to repair the third panel. Finally, the different abnormalities are marked based on the repair results, including success, failure, or non-repair, to obtain the second repair mark information.

[0123] 25. Repair the third panel according to the first abnormality marking information and the second abnormality marking information, and mark the abnormality after the repair to obtain the second abnormality marking information and the repaired fourth panel.

[0124] 26. Obtain the display priority of the mark information, and display the first abnormality mark information, the first repair mark information, the second abnormality mark information, or the second repair mark information with the highest priority on the fourth panel according to the display priority.

[0125] In the embodiments of the present application, there is no order of detection when detecting anomalies using the first and second detection methods. However, there is a display priority between the marks ultimately displayed on the panel. This reduces the number of marks ultimately displayed and prevents overlap between different marks. Furthermore, the embodiments of the present application not only use different marks to distinguish between inspections and repairs for different processes, but also integrate the inspection and repair information from the previous ones. This hybrid information provides inspection and repair prompts, avoiding the problem of lost inspection and repair information, which can lead to inaccurate detection.

[0126] Therefore, in the embodiment of the present application, it is also necessary to obtain the display priority of the marking information so as to preferentially display the information with the highest priority on the fourth panel according to the display priority, that is, to display the first abnormality marking information, the first repair marking information, the second abnormality marking information, or the second repair marking information.

[0127] In one embodiment, the priorities of the first abnormality flag, the first repair flag, the second abnormality flag, and the second repair flag are increased in order; therefore, the second repair flag is displayed on the fourth panel first, and the first abnormality flag, the first repair flag, and the second abnormality flag corresponding to the abnormality are not displayed.

[0128] In the above embodiment, the second repair marking information corresponding to an anomaly not only includes the repair result for the anomaly, but also indicates the existence of an anomaly, which is why the anomaly was repaired and has a corresponding repair result. Similarly, the existence of an anomaly also indicates that the anomaly corresponds to the second anomaly marking information. However, in the present embodiment, the second anomaly marking information is determined by comparing and matching the relay anomaly marking information with the first anomaly marking information. Therefore, if an anomaly corresponds to the second anomaly marking information, it can also be determined whether the anomaly has the corresponding first anomaly marking information.

[0129] That is, for the embodiments of the present application, the abnormality marking information and repair marking information obtained in subsequent inspections and repairs will overwrite the abnormality marking information and repair marking information in previous inspections and repairs. The embodiments of the present application can define the subsequent abnormality marking information and repair marking information by setting different meanings for different marks, so that the subsequent abnormality marking information and repair marking information include the information in the previous abnormality marking information and repair marking information, thereby integrating the abnormality marking information and repair marking information corresponding to different processes. Only a single abnormality mark or repair mark can remind the operator what specific abnormality a certain abnormality corresponds to and what treatment was performed on the abnormality.

[0130] The panel anomaly detection and display method provided by the embodiments of the present application performs multiple inspections and repairs on the panel, distinguishing the inspection and repair information corresponding to different processes and integrating the different information from the multiple inspections and repairs. This ensures that the final anomaly marking information or repair marking information includes the anomaly or repair results determined by the previous multiple inspections and repairs. Simultaneously, only the anomaly marking information or repair marking information with a higher priority is displayed. This integration of multiple inspection and repair information utilizes only the single, highest-priority marking that contains all the information and is displayed on the panel. The final displayed marking can be used to determine the panel anomaly and repair, thus avoiding information loss and discrepancies in inspection results caused by human error.

[0131] In the embodiment of the present application, after repairing the third panel to obtain the fourth panel, the fourth panel must be re-inspected for abnormalities and re-repaired. Specifically, the third panel can be re-compensated based on the second repair mark information to obtain a compensated fifth panel. Similarly, the second compensation value corresponding to each pixel in the fifth panel can be determined to obtain multiple second compensation values.

[0132] Simultaneously, a second inspection is performed on the fifth panel based on the plurality of second compensation values ​​to determine different abnormalities corresponding to the fifth panel, thereby obtaining third abnormality marking information. Simultaneously, the fifth panel is repaired based on the first abnormality marking information and the third abnormality marking information, and the abnormalities after the repair are marked, thereby obtaining third repair marking information and the repaired sixth panel.

[0133] Similarly, the display priority of the mark information is obtained, so that the first abnormality mark information, the first repair mark information, the third abnormality mark information, or the third repair mark information with the highest priority is displayed on the fourth panel according to the display priority.

[0134] That is, in the embodiment of the present application, the above-mentioned process of compensation, secondary inspection and repair of the panel is repeated until all abnormalities are successfully repaired or the repaired panel meets the requirements.

[0135] In one specific embodiment, the first detection method can be a camera photo detection API, and the second detection method can be a full contact (F / C) detection method. In this case, before driving the API device, the coordinates of the repair area of ​​the array and the initial abnormality marking information obtained by automated optical inspection (AOI) are obtained in advance. After the API device is driven, the normal photo-taking action is performed. During the final data processing, the detected abnormality needs to be compared with the initial abnormality marking information determined by the AOI to mark different abnormalities differently, thereby obtaining the first abnormality marking information.

[0136] For example, if an abnormality is detected by AOI, the API also detects it and can mark it as A0; if an abnormality is not detected by AOI, the API detects it and can mark it as A3.

[0137] After identifying the different anomalies and obtaining the first anomaly marking information, it is necessary to perform a corresponding repair on the anomaly represented by the first anomaly marking information. Based on the repair results, a repair mark is assigned to obtain the first repair mark information. For example, an anomaly that was successfully repaired is marked L1, while an anomaly that failed to be repaired or cannot be repaired in the current process is marked L2.

[0138] After the first repair process and the first repair mark information is obtained, the panel will proceed to the subsequent manufacturing process. First, the panel needs to be Vth compensated, and F / C testing is used to identify the corresponding abnormalities in the compensated panel. These abnormalities are then compared and matched with the first abnormality mark information to obtain the second abnormality mark information.

[0139] For the second abnormality marking information, different markings also represent different abnormalities. For example, B1 means the API did not detect an abnormality, but the F / C did; or B4 means both the API and the F / C detected the abnormality, and the abnormality was a point abnormality. In the embodiments of the present application, the second abnormality marking information includes the information contained in the first abnormality marking information.

[0140] After obtaining the second abnormality mark information, the panel is repaired and marked again to obtain the second repair mark information. The panel ultimately displays the mark with the highest priority among the first abnormality mark information, the first repair mark information, the second abnormality mark information, and the second repair mark information.

This ensures that the final anomaly marking information or repair marking information includes the anomaly or repair results determined by the previous multiple inspections and repairs. Simultaneously, only the anomaly marking information or repair marking information with a higher priority is displayed. This integration of multiple inspection and repair information utilizes only the highest-priority marking that contains all the information and is displayed on the panel.
